DUAL WATER CONTROL FOR FIRE-ENGINE PUMP.

Application med July s,

To aZZ whom t may concern.'

Be it known that I, ALBERT B. HOUSE, a citizen of the United States, residing in the borough of Brooklyn, of the city of New' York, in the State of New York, have invented certain new and useful Improvements in Dual Water Controls for Fire- Engine Pumps, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.

This invention has for its principal object to provide a dual Water control for fire engine pumps by means of which the usual valve on the discharge side of the pump may be actuated by the attendant from either side of the truck. A further object of the invention is to provide a dual control for permitting the actuation of the bleed valve in the discharge side of the pump from either side of the truck. The improved apparatus for accomplishing this dual control will be described in connection with one embodiment thereof shown in the accompanying drawing, in which- Figure 1 is a view of so much of a motor fire apparatus as is necessary for an understanding of the applic-ation of the improved control to the fire pump.

Figure 2 is a view in rear elevation showing only the fire pump and the association therewith of the improved control, the view beingtaken along the plane indicated by the line 2-2 of Figure l and looking in the direction of the arrows.

Figure 3 is a view in plan of so much of the apparatus as is shown in Figure 2.

The lire truck a has mounted thereon at, any suit-able point a fire pump indicated somewhat conventionally at b to which lead inlet pipes c, d, from each side of the truck to permit the attachmient thereto of the inlet hose e, depending upon the position of the hydrant with respect to the truck. The pump Z9 is also provided with two discharge pipes f, g, to either one of which may be attached the fire hose /L to permit the .water to be led off at either side as desired. Each of the discharge pipes f, g, has mounted therein a suitable control valve indicated in the drawings by the T-couplings 7c. These valves are controlled by actuation of shaft-s 7c connected operatively thereto and adapted to be actuated conveniently as by hand wheels 2, 762 fixed thereon, respec- 1819. Serial No. 309,488.

tively. One feature of the invention resides in the association with the actuating shafts le', which, it will bevunderstood, are l0- cated at opposite sides of the truck, of actuating devices to permit their operation from the opposite sides of the truck, respectively. In the illustrated embodiment the shaft has keyed thereon a. bevel pinion 3 with which engages a bevel pinion Z keyed on the end of an operating shaft Z which extends transversely of the truck and has at its end on the opposite side of t-he truck from the shaft a suitable operating member, such as a hand wheel Z2. In like manner, the shaft lo carries a bevel pinion k3 which is engaged by a bevel pinion m carried on the end of a transversely extending shaft m on the end of which is fixed a hand wheel m2 within convenient reach of the operator at the opposite side of the truck from the shaft c. The shafts Z may be journaled in a two-part .gear box 4 which encloses the pinions 3, Z, and the shafts c, m may be journaled in a two-part gear box kt which encloses the pinions 7c3, m.

In the discharge pipes g of the pump b are included bleed valves n, o, respectively, adapted to be controlled by hand levers n', o, respectively. The purpose of these bleed valves is to permit a sufficient leakage of water therethrough to reduce substantially the pressure within the fire hose, as when this hose is being moved by the firemen from one position to another. These Valves n, o, are located between the control valves i, 1, respectively, and the fire hose so that it ecomes immaterial whether both of the valves are opened at the same time, one of the valves always serving its intended purpose. according to the side on which the water is being discharged.

Another feature of the invention resides in the provision of devices for opening these valves n, 0 from either side of the truck. [n the illustrated embodiment, the operating levers n', 0 are interconnected by a link y) which extends therebetween transversely of the truck.

From the description given it will be evident that while the improved devices are simple in character the inventive thought which resides primarily in their provision marks a distinct advance in this art since it enables a single attendant at the fire truck to answer signals and effect instantly the desired control of the discharge regardless of his position With relation to the valves to be operated. His duties might, for instance, require his attention to the inlet hose e and when he is on that side of the truck which is remote from the discharge valve z' Which might be in use at the time, he would be `unable to effect a quick control of that valve or of the bleed valve n Without passing entirely around the truck and, perhaps, neglecting some. matter Which requires his mmediate attention at the opposite side. Under the conditions to be met in fighting fires it will be appreciated that Jfactors of the kinds stated often assume great importance in a crisis.

I claim as my invention:

l. In combination with a lire pump having a Water inlet, of discharge pipes eX- tended from the pump in opposite directions, a valve for each pipe near the ends remotest from the pump, operating means adj acent each valve, controllers adjacent said valves, and means operatively connecting the controller of an adjacent valve With the operating means of a remote valve.

2. The combination claimed in claim l, including controllers adjacent the valves, each controller operatively connected with the operating means of the valve adjacent said controller.

eratively connected with those of a second j pair.

4. In a fire truck, in combination With the pump provided with a Water inlet, discharge pipes extended from the pump transversely of the truck provided with outlets on opposite sides of the truck, a valve near each outlet, an adjacent pair of controllers at each side of the truck, means at each valve for operating the same, meansv operatively connecting one of 'an adjacent pair of controllers with the operating means of the valve of an adjacent outlet and the other With the operating means of the valve at the opposite outlet. l

5. The combination claimed in claim 4, including bleed valves adjacent the outlets.

6. The combination claimed in claim 5, including valve operating means adjacent each bleed valve.

' 7. The combination claimed in claim 6, including a rod connecting said operating means.

This specification signed this 30th day of June, A. D. 1919.
